Question

A heat engine having 10.0 moles of ideal monatomic gas as a workingsubstance has a cycle
consisting of the following three processes: isobaric expansion at200 kPa with volume change from
0.10 m3 to 0.23 m3, an isometric process at 0.23 m3 with pressurechange from 200 kPa to 50 kPa, and
an addibatic process. (a) Draw the cycle on a P-V diagram. (b) Findthe temperatures at points A, B
and C. (c) Find the internal energy at points A, B, and C. (d) Findthe work done by the engine for
each process and the amount of heat flowing into or out of thesystem for each process. (e) Find the
total work done by the engine and its efficiency.
